The North East seems to have been omitted from the high tech resurgence. I actually work for a company in San Jose' (get to spend lots of time flying between the coasts). Everyone is hiring in San Jose' for technology positions. The issue is that the venture investment in the North East has been minimal and many established companies are on the wane. The biotechnology wave has fizzled and we have not done much in clean technology. The hot area appears to be social networking and that all went to the West Coast. Social gaming companies are off the charts right now.
Your read on India and China is absolutely right. No loyalty and high levels of mobility. The West Coast mentality is not too much different.
